Special Issue Information
Dear Colleagues,
Recent years have witnessed significant progress in photoacoustic sensing technologies, driven by the growing demand for accurate, sensitive, and compact systems for environmental monitoring. While traditionally focused on trace gas detection, the scope of photoacoustic sensors has rapidly expanded to include a broader range of air quality indicators such as particulate matter, volatile organic compounds (VOCs), humidity, and aerosols. This Special Issue aims to highlight cutting-edge research and development in photoacoustic-based sensing systems designed not only for gas detection but also for holistic air quality assessment in both indoor and outdoor environments.
In addition to environmental applications, contributions addressing the use of photoacoustic sensors for breath analysis and medical diagnostics are also encouraged, reflecting the versatility of these technologies in health-related monitoring. We invite submissions covering novel sensor designs, miniaturization techniques, multi-species detection strategies, integration with IoT platforms, data analysis algorithms, and field deployment case studies. Interdisciplinary approaches combining materials science, photonics, acoustics, and environmental or biomedical science are particularly welcome. The objective is to provide a comprehensive overview of the current state and future potential of photoacoustic technologies, sensors, and sensing system design, as well as novel photoacoustic measurement strategies as a versatile and powerful tool in both environmental and health-related sensing.
This Special Issue invites contributions that address various aspects of research and development related to photoacoustic-based sensing. The scope and applications include, but are not limited to, air quality and environmental monitoring, biomedical imaging, combustion monitoring, workplace safety, agriculture and food monitoring, clinical/medical applications such as breath monitoring, and industrial inspection for gas and liquid sensing.

Manuscript Submission Information
Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.
Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Sensors is an international peer-reviewed open access semimonthly journal published by MDPI.
Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2600 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
